Remember the republicans control Virginia and the elections right now. It is more likely Bob McDonnell and Bill Bolling have their dirty hands in this than the democrats. This was supposed to be Bolling’s year he has been waiting a decade for and they hate Cuccinelli for ruining that. There is also precedent from the 2012 primaries where they were successfully able to keep everyone but Romney off the ballot. We have reached a point where the establishment republicans may well be a bigger enemy than the democrats themselves.
This has always been the case.
